Testing a 100Mb connection between scorpio and bort.

WLAN

It has been said that the FritzBox 7312's WLAN is okay for a flat, but too weak for a house. The FritzBox 7270's WLAN is supposed to be strong enough for a house, it has three antennas etc.. I wanted to test this. So I put my Latitude 2100 into a cellar room and started the command

iwlist scanning | grep -Ei "quality|essid"

I used the same command with a FritzBox 7312 and with a FritzBox 7270 with the same laptop with the same distribution on the same position, same kernel etc.. I verified every result at least 3 times to make sure variance is low.

The results were

Wii

I have driven the Luigis Piste course on Nintendo Wii and chosen different cars and different figures (Bowser and Yoshi). Here are the times:
Bowser in Offroader on Luigis Piste: 1.28
Bowser in Offroader on Luigis Piste: 1.28
Bowser in Offroader on Luigis Piste: 1.28
Yoshi in Nostalgia on Luigis Piste: 1.28
Yoshi in Bopper-Bolide on Luigis Piste: 1.28
Seems I always need 1.28 on Luigis Piste.
